This project assesses the effectiveness and lasting impact of combining Dialectical Behavioral Therapy (DBT) with prefrontal repetitive transcranial magnetic stimulation (rTMS) in patients with borderline personality disorder.
The proposed project aims to evaluate the effectiveness of combining Dialectical Behavioral Therapy (DBT) with prefrontal repetitive transcranial magnetic stimulation (rTMS) in individuals with borderline personality disorder (BPD). The study includes four groups of patients: 1) DBT combined with active prefrontal rTMS treatment (rTMS-DBT group), 2) DBT combined with sham rTMS treatment (sham-DBT group), 3) active prefrontal rTMS treatment only (rTMS-only group), and 4) sham rTMS treatment only (sham-only group). The study will include assessments conducted before (T1) and after the rTMS treatment (T2) composed of self-reported questionnaires, clinical interviews assessing self-harming behavior and healthcare utilization, ecological momentary assessment of emotional variability, functional magnetic resonance imaging (fMRI) during emotional task, and control clinical EEG measurements. Follow-up measurements will be conducted at T3 (three months after rTMS), and for DBT group also at T4 (six months after rTMS), and T5 (twelve months after rTMS) for to track long-term effects.

Dialectical behavioral therapy (DBT) program with all the standard DBT modules (individual therapy 1 hour per week, skills group 3 hours per week, phone coaching, and therapist consultation team 1,5 hour per week). The program takes 24 weeks in total comprising two 12-week runs of skills training. The program will be precluded with 4 individual sessions of pretreatment before the start of the main program part.
rTMS will be performed by DuoMag XT with 70BF cool coil. Patients will undergo 15 daily stimulation sessions during a period of three weeks with one session each working day. Each session consists of 20 trains with 100 pulses (10 seconds for train). Inter-train interval will be 30 seconds. Gradual titration of the individual resting motor threshold (RMT) will apply, meaning probands will undergo first session with 90% RMT intensity, second session with 100% RMT intensity, third session with 110% RMT intensity. All the following sessions will use the final 120% RMT intensity. In case a session is left out because of any reason, the total duration of treatment will be prolonged by one day, so that the total number of sessions underwent is the same in all patients. Patients will receive 2000 pulses during one session (total 30000 pulses during the whole procedure) with 10 Hz frequency.

Sham TMS will be performed by sham coil that looks identical to DuoMag XT in the active group. Patients will undergo 15 daily sham stimulation sessions during a period of three weeks with one session each working day. Each session consists of 20 trains with 100 pulses (10 seconds for train). Inter-train interval will be 30 seconds.

Increased regulation of amygdala during fMRI neurofeedback
fMRI neurofeedback will be used to measure the participants' ability to influence their amygdala activity. fMRI neurofeedback is a method which enables measuring, computing, and displaying the current blood oxygen level-dependent (BOLD) signal level in a selected brain area. The ability of the participants to voluntarily regulate the target area activity using the feedback presentation is measured. Specifically, pictures arousing negative emotions will be presented to participants in the MR scanner together with a scale showing the current level of their right amygdala activity and participants will be instructed to decrease the scale as much as possible by regulating down their emotion (regulation condition). As a controlled condition to regulation condition, passive viewing of the negative pictures will be included (view condition).
Time frame: Baseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3) in all groups and additionally 24 weeks after baseline (T4) in DBT group
Decreased brain emotional reactivity
Hariri task (fMRI emotional processing task) in fMRI will be used to measure brain correlates of emotional reactivity. The task includes 2 experimental categories: 1. emotional faces and 2. emotional social scenes which reliably evoke emotional responses, and 1 control baseline condition of geometric shapes. Further, each experimental category will include three condition: negative pictures, positive pictures, and neutral pictures. Contrast of emotional conditions against neutral conditions of the same type and against control condition will be used to track the neural correlates of emotional reactivity and processing.
Time frame: Baseline (T1), after 3 weeks (T2), 12 weeks after baseline (T3) in all groups and additionally 24 weeks after baseline (T4) in DBT group

fMRI Go/No-Go task will be displaying 2 experimental conditions (presenting letter A or X), where participant is asked to react with a button only in first condition (Go condition), while remain passive during the second condition (NoGo condition). The task is designed to measure impulsivity and brain correlates during inhibition.

Participants will be asked about their current experienced emotion and its intensity. Additional questions on self-harm and suicidal thoughts intensity during the day and whether a self-harming incident has occurred during the day will be sent at 9 pm on both days.
